The Japanese ex-patriates I worked with for years, all extremely educated people, were never instructed about WW II (in school) except for brief mentions of the ETO. Those who learned about the war mainly did so via their own research. My friend Itakura was a huge armor expert and modeler. He had nightmares about a Great Great Grandfather who had been a Samurai for one of the old warlords. The G G Grandfather had led a massacre in Fukuoka Prefecture, Kyushu, back in the day.
